Inert's PF-1 Powder Filtration System Enables Safe Handling

Inert displays its PF-1 powder filtration system, integrated with a PowderShield enclosure and Argon-2 gas management system. Working in a closed-loop configuration, these systems enable additive manufacturers to safely postprocess metal 3D prints; reclaim and reuse costly metal powders; maintain a strict O₂ and H₂O argon gas atmosphere of less than 1 ppm; and facilitate other sensitive powder-handling and 3D printing processes.

The powder filtration system is equipped with safety features such as a quad HEPA filter cluster to collect reactive powders, water passivation of particulate, isolation valves and an electrically grounded design that prevents static electricity buildup or potential ignition of particles. Other features include an easily accessible lockable cabinet, stainless steel piping, 60-cfm blower, and magnehelic gage to display pressure and indicate when the filter needs replacement.

The PF systems are available in a variety of models that can be tailored to different needs. PF-1 is said to be well-suited for removing soot created as a byproduct of laser welding or 3D printing. PF-2 has a higher maximum flow rate for larger industrial additive manufacturing processes, and PF-3 contains a ceramic filter that can be safely used with higher temperatures.
